RAPID Linked geomorphic-ecological disturbance response as a driver of alterations in aquatic-to-terrestrial energy flux: consequences of dam removal on a mid-size river

大坝的拆除为研究河流如何应对环境干扰提供了一个极好的机会。尽管拆除大坝作为一种河流恢复方法越来越受欢迎，但许多生态系统的反应在很大程度上仍然未知。该RAPID项目将调查大坝拆除对河道地貌短期（1.5年）响应和水陆碳能量流动的影响。为了做到这一点，将在俄亥俄州哥伦布市的一条中等大小的河流中研究水陆食物网，那里最近拆除了一座大型低洼水坝。研究小组在大坝拆除前三年就在研究系统中收集了数据，因此有能力进行这项研究。大坝拆除对水陆联系、食物网和河岸生态系统群落的地貌影响代表了一项新的研究，该研究建立在有记录的鱼类和其他水生生物群落在大坝拆除后的变化基础上。所提出的工作的智力价值在于确定大坝拆除的干扰如何驱动相互关联的河流-河岸反应。通过加深我们对大坝拆除对生态系统功能干扰的短期影响的理解，本研究将有助于在人类主导的环境中维护和/或恢复河流。该项目包括本科生和研究生的参与，并将研究结果纳入俄亥俄州立大学（OSU）的课程。此外，传统上不接触研究和STEM活动的当地高中生将通过与俄勒冈州立大学的“向上束缚”计划的现有合作伙伴关系参与项目研究活动。研究小组还将在俄勒冈州立大学的Shiermeier Olentangy河湿地研究公园举办一个水坝拆除研讨会。该研讨会将讨论大坝拆除的生态后果，并将涉及公众、当地流域团体、城市规划者和机构人员。

Dam removal provides an excellent opportunity to study how rivers respond to environmental disturbance. Despite the increasing popularity of dam removal as a river restoration approach, many ecosystem responses remain largely unknown. This RAPID project will investigate the influences of dam removal on short-term (1.5 years) responses in channel geomorphology and aquatic- to-terrestrial flows of carbon and energy. To do this, linked aquatic-terrestrial food webs will be studied in a mid-size river in Columbus, OH, where a large, lowhead dam was recently removed. The study team is well positioned to conduct this research, having collected data in the study system three years prior to dam removal. The geomorphic influence of dam removal on aquatic-terrestrial connections, food webs, and riparian ecosystem communities represents novel research that builds on documented community shifts in fish and other aquatic biota following dam removal. The intellectual merit of the proposed work lies in establishing how the disturbance of dam removal drives linked river-riparian responses.By advancing our understanding of the short-term effects of the disturbance of dam removal on ecosystem function, this study will contribute to efforts to maintain and/or restore rivers in human-dominated environments. The project includes involvement of undergraduate and graduate students and inclusion of study findings in The Ohio State University (OSU) coursework. Additionally, local high school students not traditionally exposed to research and STEM activities will be engaged in project research activities through an existing partnership with OSU's Upward Bound program. The study team will also deliver a dam-removal workshop run out of OSU's Shiermeier Olentangy River Wetland Research Park. This workshop will address ecological consequences of dam removal and will involve the public, local watershed groups, city planners, and agency personnel.
